Abstract

Designing and exploiting collaborative learning activities indicators is a strong challenge for technology-enhanced learning. We propose an original approach, guided by the models of interaction’s traces and exploited by Trace Based Management System. Designing an indicator consists in explicitly modelling the interaction’s trace in order to provide observables for it. Therefore, effective implementation of the indicator consists in explaining the needed transformations on available interaction’s traces (primary modelled traces), until being able to formulate the indicator computation. A «path» of transformations is explicitly designed and applied for both document and perform the calculation of the indicator. A library of enriched models indicators (platform independent) with their transformations sequence (context dependent) are available for reuse and share. Our approach is illustrated on the Moodle platform in order to explain the practical use of the proposed contribution for collaborative activities.
